Title: Ribbon cable of run water prevention type
Inventor: FUJITANI KENSHO
IPC: H01B7/282
Filed: 1988-09-05
Abstract: PURPOSE:To prevent the enlargement of water immersion by surrounding a stacked body or the aggregate thereof of core wire ribbon of a ribbon type cable, with a water absorbing resin composite tape. CONSTITUTION:In a ribbon type cable, at least one piece of superposed body 3 is wound by a water-absorbing tape together with water-absorbing wire-like body 5, and in the case that the body 3 is composed of a plurality of pieces, the aggregate is wound by a water-absorbing tape 12 together with a water- absorbing wire-like body 11. The tape and water-absorbing wire-like body are composed respectively of water-absorbing high molecular composite body formed by polymerizing soluble ethylene unsaturable monomer impregnated in or applied to a support body to be processed in the form of tape or wire. Since the water absorbing high molecular composite body swell speedily when they absorb water, the volume of cable tends to increase at the time of generation of water immersion upon breakage of outer part of cable. It is thus possible to prevent the enlargement of water immersion effectively.

Title: Biological refining method of waste air flow
Inventor: FUERITSUKUSU BUORUFU
IPC: B01D53/00
Filed: 1991-08-08
Abstract: PURPOSE: To prevent a pH value in a biofilm from excessively lowering and to secure passages in a trickling filter so as not to be clogged by liquid flow by intermittently wetting the trickling filter. CONSTITUTION: A waste gas 2 is introduced from an upper part of a trickling filter tower 1 to be uniformly distributed. Microorganism is fixed at a trickling filter 5 and wetted by a series of spray nozzles 6. Liquid is collected in a sump 8 and recirculated to the spray nozzles 6 by a pump 9. In this case, if the distribution of the liquid for packings is too small, a biofilm is acidified to cause the decrease in decomposition activity of the microorganism. If distribution density is to high, the liquid preferentially clogs the passages containing a lot of biomass to degrade the distribution property. In order to prevent this, the pump 9 is not operated continuously but intermittently. The retention time and frequency for wetting cycle depend on the property and extent of pollution of the gas.

The value of each block of 5-ms delayed pictures is calculated in a stage 18 by using the output of the delay 16 and the value of each block of 15ms delayed pictures are calculated in a stage 20.  For example, the two outputs of the stage 18 which are separated from each other by the one-line internal at a delay 19 are respectively impressed upon the inputs of an intermediate filter 22 and the other input of the filter 22 receives the output of a stage 12. Similarly, an intermediate filter 24 receives the two outputs of a stage 14 which are delayed from the output of the stage 20 by the one-line interval at a delay 15.

Title: Method and device for preventing overheating of inverter cooker
Inventor: PAAKU JIYOUN IN
IPC: H05B6/06
Filed: 1994-09-19
Abstract: PURPOSE: To prevent overheating of an inverter cooker by comparing difference between a voltage corresponding to a temperature detected by a bottom sensor at a metal pan and a reference voltage to a set cooking temperature with a cooking process completion counting value. CONSTITUTION: As completion of soaking, boiling, and steaming is detected by a first to a third counters based on input from a system clock CLX, switches SW1-SW3 are closed, and output of a switching part 5 is inputted to one of an AND gate 6. A voltage to a temperature detected by a bottom sensor 1 at a metal pan is compared with a set reference voltage (Vref) for each process to be inputted to the other of the AND gate 6. By output of the AND gate 6, a power supply part 7 is actuated to drive an inverter. In the case where foreign matter exists between the bottom sensor 1 at the metal pan and the metal pan, output of the bottom sensor 1 becomes smaller, and the AND gate 6 stops outputting. Delay of a rice boling process is thus prevented, thereby overheating of an inverter cooker is prevented.
